srncrrron'rron forming part of Letters Patent No. 629,357, dated July 25, 1899.

Applicatipnfiled March 4,1899. gerial a. 707,703. (No model.)

To all whom it may concern:

Be it known that I, HARRY l\I.-HAMRIcK,.a citizenof the United States, residing in the city and county of Ph'iladelphia,State of Pennsylvan'ia, have inventeda new and useful Improvement in Burners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to burners which are adapted to be used in connection with gasolene or other hydrocarbon; and it consists more especially of a novel manner of locating and supporting the reservoir for the hydrocarbon and also the compressed-air reservoir adjacent thereto, said reservoirs being supported upon the globe of the lamp at a point near or above the burner thereof, whereby itwill be apparent that the hydrocarbon can flowtothe burner by the force of gravity, which latter is augmented by the pressure of the com pressed air in the adjacent'reservoir.

To the above ends my invention consists of an improved construction of compressed.

air and hydrocarbon reservoirs which are preferably arranged above the lamp and supported upon the globe thereof,the compressedair reservoir being suitably connected to the hydrocarbon-reservoir and the. latter tothe burner. J

It further consists of novel details of cone struction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a perspective view of a burner,showing the compressed-air and bydrocarbon reservoirs embodying my inv en tion and also a portion of a lamp and globe to which the same are applicable. Fig.2 represents, on an enlarged scale, a section on line asw,Fig. 1. Fig. 3 represents a section on line y y, Fig. 2.

Similarletters of reference indicate corremay be employed, and therefore a further detailed description of the burner is unnecessary, since the same forms per so no part of the present invention.

B designates a supply-pipe provided-with a valve 0-, which leads from the burner to the hydrocarbon-reservoir D, which latter is filled through a'suitable inlet E.

'F designates a reservoir for compressed air, the same consisting of the members or compartments G,H, and J ,which are preferably arranged so that their casing forms a continuity of the casing of the hydrocarbon-reservoir I) which latter is separated from the portions G and J of the compressed-air reservoir by means of the partitions K.

- Ldesignates a connection leading'from the compressed-air reservoir to the u pper. portion I "air and hydrocarbon upon the upper portion of the lamp-frame N, wherefrom it will be apparent that the hydrocarbon in addition to being fed by gravitywill also be subjected to air-pressure upon the top thereof, whereby it will always be subjected to a positive pressure suflicientto force it through the conduit B downwardly to the burner A.

The operation is as follows: The reservoir D is filled with hydrocarbon to the desired extent, the valve 0 being closed, after which the chambers G, H, and J are filled with compressed air through the opening M. Upon properly manipulating the valve C it will be apparent that the hydrocarbon will. be directed to theburner A in the desired quantity, and by proportioning the size of the hydrocarbon-reservoir D and the compressedair reservoir Fit will be apparent that I can charge the reservoirs at each filling so that the light will burn for a predetermined period, which is advantageous when it is detry of the lamp.

sired to use the lighting apparatus in districts where it is intended that the apparatus should burn for only a predetermined period.

By arranging the hydrocarbon and compressed air reservoirs in the manner described it will be apparent that the same can be readily applied to existing lamps or burners without necessitating any change therein, and the same, furthermore, do not detract from the general appearance or symme- The reservoir can be placed upon lampglobes which are round, oval, or any other similar contour, as is evident.

If desired, I may connect the pipe P with. the compressed-air inlet M,,said pipe extending downwardly within the lamp-globe and being continued through the lamp-post to a point near the base of the latter, Wherebythe air-pump or compressed-air supply can be readily attached thereto.

It will be apparent that slight changes may be made in the manner of supporting and equipping lamps with hydrocarbon and com-' pressed air reservoirs constructed as described, and I therefore reserve to myself the right to make all such changes as come within the scope of my invention.

In practice I prefer to employ the pipe P, which is attached to the nipple M and may extend downwardly to the lam p-post for connection for a pump at the base of said post,

2. The combination of a burner, a globe surrounding the same, reservoirs for compressed air and hydrocarbon supported upon said globe so as to form a continuation of each other, said compressed-air reservoir being separated from the hydrocarbon-reset voir by partitions, a communication between the upper portion of the compressed-air reservoir and said hydrocarbon-reservoir, and a valved conduit leading from thelatter to the burner. 3. The combination of a compressed-airreservoir, a hydrocarbon-reservoir D forming a continuation of said compressed-air reservoir and separatedtherefrom by the partitions K, an inlet leading from said compressed-air reservoir to the upper portion of the hydrocarbon reservoir, inlets for supplying compressed air and hydrocarbon to said reservoirs' respectively, a burner located within the lamp-frame below said reservoirs, and a valved conduit leading from the hyd rocarbonreservoir to said burner.

4. A lamp-frame, a casing surrounding the same and divided interiorlyso as to form communicative reservoirs for compressed air and hydrocarbon, a burner supported below said casing, and avalved conduit leading from the hydrocarbon-reservoir to said burner.

5. The combination ofa post; a lamp-frame, a casing supported thereon and adapted to surround the same, said casing being divided interiorly so as to form com munieating reservoirs for compressed air and hydrocarbon, a burner supported below said casing, a conduit leading from said hydrocarbon-reservoir downwardly to said burner, and an air sup- -ply pipe leading downwardly from said compressed-air reservoir through said post for voir.
